Yes, it is possible to get celebi but you need to have the Japanese version.
The only game you can currently get Celebi in is Emerald version (until the Celebi event happens for HG/SS).
Celebi isn't obtainable in Sapphire Version. You can only get it through a promotional event.
No, Celebi or any other Legendary Pokemon can't have an egg.
You cannot get Celebi in the American version of Pokémon Colosseum. Japan was also to receive it in the Japanese version of Pokémon Colosseum because they had included a bonus disc that would have unlocked Celebi as an in-game download however Nintendo of America opted to go with a Pokémon Bonus Disc that would download a Jirachi to American versions of Pokémon Ruby and Pokémon Sapphire.
